Agile Antechinus
I accidently trapped an agile antechinus between our back door and the screen door.
Antechinus are protected species and soon after videoing this I let the antechinus free outside.
I have some audio recordings of antechinus calling that I can post up too once I get a chance to go through the recordings and do some editing. They make a high pitched sound between 10kHz and 15kHz.
